Play select games from the ST Math fifth grade curriculum. Concepts include volume, order of operations, and more.

## Measuring Volume

Find volume of rectangular prisms.
• Develop concept of volume measurement using cubic units.
• Levels begin with simple 3-D objects composed of cubic units, then advance to finding volume using dimensions of rectangular prisms.
• Use a multiplication formula for finding volume.

## Order of Operations Using Parentheses

Use parentheses in expressions to build visual models.
• Understand the use of parentheses in determining order of operations.
• Given a visual model, determine the order of operations for generating the model.
• Levels begin with two-step expressions using addition and multiplication, then progress to multi-step operations.

## Adding Fractions with Unlike Denominators

Develop strategies for adding fractions with unlike denominators.
• Use visual fraction models to create common denominators for adding fractions with unlike denominators.
• Levels begin with modeling sums of fractions with like denominators, then advance to creating visual models using both unlike denominators for partitioning an area model.

## Coordinate Trap

Plot points on a coordinate plane and write ordered pairs.
• Plot points in a coordinate plane given an ordered pair.
• Write ordered pairs given a point on a coordinate plane.
• Feedback animates the role of ordered pairs in plotting points.

## Fraction Multiplication on Number Lines

Estimate products of fractions and whole numbers on a number line.
• Develop concepts and strategies for multiplying fractions by whole numbers and whole numbers by fractions.
• Multiplication of a fraction by a whole number can be modeled by iterating a given fraction.
• Multiplying a whole number by a fraction can be modeled by dividing the whole number by denominator and multiplying by numerator.

## Measurement Conversion

Convert within customary units of volume
• Convert within customary units of volume: Gallons, Quarts, Pints, Cups.
• Levels begin with simple conversions of 1 larger unit to smaller units, then advance to converting fractional amounts of a larger unit to smaller units ( 1 ½ gallons = __ cups).
